S Shuttle
The S Shuttle is a light rail service on the Muni Metro system in San Francisco, California. The service began in 2001 as the S Castro Shuttle, an effort to reduce crowding at Castro station. It was briefly discontinued in 2007 when the T Third Street line was opened. Service was extended to St. Francis Circle station in 2013, but cut back to West Portal station in 2016. In 2020, it was changed to full-time service as part of a reconfiguration of Muni Metro service. The designation of S Shuttle is also given to trains at other hours and locations, most commonly to those which run service before and after San Francisco Giants and Golden State Warriors games to provide additional capacity to Oracle Park and Chase Center respectively.

S Shuttle Crossing Over Near West Portal, June 2017
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Subway (San Francisco)
The Central Subway is a Muni Metro light rail tunnel in San Francisco, California, United States. It runs between Chinatown station in Chinatown and a portal in South of Market (SoMa), with intermediate stops at Union Square/Market Street station in Union Square and Yerba Buena/Moscone station in SoMa. A surface portion runs through SoMa to connect to the previously existing T Third Street line at 4th and King station. The project was initiated after the Embarcadero Freeway was torn down following the 1989 Loma Prieta earthquake, as activist Rose Pak "almost single-handedly persuaded the city to build" the Central Subway to compensate Chinatown for the loss of the fast cross-town connection. Originally set to open in late 2018, the subway initially opened with a weekend-only shuttle service between Chinatown station and 4th and Brannan station on November 19, 2022. Full service as part of the T Third Street line began on January 7, 2023. With the addition of the Central Su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Splice
In telecommunications, a line splice is a method of connecting electrical cables (electrical splice) or optical fibers (optical splice). Splices are often housed in sleeves to protect against external influences. Splicing of copper wires The splicing of copper wires happens in the following steps: * The cores are laid one above the other at the junction. * The wires are wrapped two to three times around each other ( twisting). * The core insulation is removed. * The bare veins on a length of about 3 cm "strangle" or "twist". In some cases, the strangulation is soldered. * To isolate the splice, an insulating sleeve made of paper or plastic is pushed over it. The splicing of copper wires is mainly used on paper insulated wires. LSA techniques (LSA: soldering, screwing and stripping free) are used to connect copper wires, making the copper wires faster and easier to connect. LSA techniques include: * Wire connection sleeves (AVH = Adernverbindungshülsen) and other cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Wire
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
